Two 80Ni · 20Cr‐type alloys, one 99.99% pure and one with 98% purity, formed a multilayer oxide scale with an outer layer of NiO and a single‐layer scale with outer portion richer in Cr 2 O 3 , respectively. An applied K‐aluminosilicate glass at 1020°C penetrated the latter oxide scale. Adherence was present at all interfaces due to the existence of chemical equilibrium. Fracture occurred in the multilayer oxide scale and in the glass close to the oxide glass interface, respectively.
